Patented June 21, 1932 UNITED STATES PATENT OFFICE FRIEDRICH W. F. BERGER, OF BERLIN, GERMANY, ASSIGNOR TO THE NATIONAL CASH REGISTER COMPANY, OF DAYTON, OHIO, A CORPORATION OF MARYLAND CASH REGISTER Application fi1ed".lu1y 20, 1927,8eria1'1t0. 207,248, and in Germany August 11, 1926.

This invention relatesto improvements in cash registers, and isshown applied to the type shown and described in Letters Patent of the United States, No. 1,619,796 issued to 5 B. M. Shipley on March 1, 1927.

'One' object of this invention is to provide novel means for preventing the insertion of a slip into the machine when the machine is adjusted to take one impression to be made only on a detail strip which remains in the machine, thereby preventing the taking of the impression intended for the detail strip, on an inserted slip;

Another objectis to provide novel mechanism for opening the slip receptacle when the machine is adjusted to take two impressions; one of which is made on the inserted slip and the other on the detail strip retained in the machine.

lVith these and incidental objects in view,

the invention consists of certain novel features of construction and combinations of parts, the essential elements of which are set forth :in appended claims and a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany and form part of this specification.

Of said drawings:

General description In machines of the type to which this invention is shown applied, the upper print- H ing hammer (the one shown in the present disclosure) is adapted to be controlled to take either one or two impressions. I In either case, one impression must be made on the detail strip which remains in the machine. w I This is to insure a permanent record of every transaction. When two impressions are taken, the first is taken on a check which is automatically ejected from the machine immediately after the impression is made. The second impression is then taken on the detail strip. Such is the case in the Shipley patent above referred to.

The present disclosure does not contemplate the issuing of a check, by this mecha nism, but is adapted to receive a slip inserted by hand. Upon operation of, the machine, the slip receives the first impression and is then ejected from the machine by the eject ing mechanism disclosed in saideShipley patent. The second impression is then taken, as usual, on the detail strip.

The present case discloses mechanism which prevents the insertion of a slip for operations wherein the hammer makes only one impression, and enables such insertion for operations wherein the hammer makes two impressions. Thus it is not possible for the operatorto insert a slip for an operation wherein only one impression is made, and thus prevent the recording of this transaction on the detail strip.

When the present mechanism is used in connection with the said Shipley patent, it is intended that the mechanism disclosed therein to control the upper impression hammer for one or two operations be suitably notched so that during adding operations, depression of only the list key will cause two impressions, and so that during totaling operations only a moving of the total lever to the reset position for the 'first transaction bank will cause two impressions. To so notch this mechanism is but a matter of choice, as will be apparent upon an understanding of the mechanism of said patent.

facilitating such insertion;

wrapped around ashaft 41 to form a sleeve With the impression hammer so controlled, it becomes necessary to prevent the insertion of a slip at all times except when the machine is to add with the list key depressed, or is to reset a totalizer controlled by any of the keys in the first transaction bank. The mechanism for preventing .a wrongful insertion is fully set out in the detailed description, to follow.

.Pm'nte'r mechanism The machine is provided with a plurality of type carriers loosely mounted on a rod 31 (Fig. 1) Each type carrier is differentially adjusted under the control of an amount key or transaction key in the well known manner as is shown and described in the above mentioned Shipley patent. A printing hammer 32 is provided, adapted to take one or two impressions from the type carrier 30, as controlled by the transaction keys and by the total lever. The means for effecting this control are not shown, and for a description and illustration of said means, see the above mentioned patent.

A detail strip 33 is guided around the .impression hammer by two rollers 34 and a plate 35. The .machine is so constructed that when the impression hammer receives but one operation, the impression will be taken on the detail strip 33, and when it receives twooperations, two impressions will beimade, .One-on-the detail strip 33and the other on an insertable slip. Thus, an impression will be taken on the detail strip during each operation of the machine, and on the inserted sliponly during those-operations in which a slip can be inserted in the machine.

A slip table 36 is provided upon which the insertable slip is placed when an impression is to be taken thereon. The cabinet 37 is formed with an opening 39 through which the slip can be inserted, a guide flange 38 A strip is 67 having a lip 40 normally obstructing the opening 39 so that no slip can be inserted into the receptacle. The sleeve 67 is secured to and adapted to be operated by an arm 42, as

will be hereinafter described, when the list key 43 (Figs. 1 and 3) is depressed.

The list key 43 is slidably mounted in the key frame 44 carried by two rods 45. The

key 43 is provided with a pin 46 adapted to engage a cam-edge 47 of an arcuate bar 68 secured toan arm 48'pivoted on a rod 66. Depression of the key 43 by the pin 46 co-operating with the cam edge'47, moves the bar 68 upwardly, thereby rocking the arm 48 clockwise. Alink 50 pivoted to the arm 48, is also connected to a pin 69 carried by arms: 49 and 52 (Fig. 1) pivoted on ashaft 53 supported by the side frames (not shown) of the machine. The arms 49 and 52 are connected by a yoke or bar 70, to move in unison. These arms 49 and 52 also carry a ball-headed pin 51 engaged by an arm 54 secured to a shaft 55 carried by the frames 56 and 57. Also secured to the shaft 55 is an arm 58 provided with a stud 59, which cooperates with an arm 60.1oosely pivoted on the shaft 55. The arm 60 is connected to a bell crank 61 by a link 62.

"The arm 60 is normally held against the stud '59 by a spring 63. The bell crank 61 is loosely pivoted on a rod 64' and isconnected to the arm 42 by a link 65.

From the above it can be seen that when the list key 43 is depressed,.and the arms 48, 49 and 52 are rocked clockwise, the arm 54, shaft 55 and arm 58 are rocked clockwise, thus moving the arm 60 clockwise. The clockwise movement of the arm 60, through the link 62,transmits clockwise movement to the bell crank 61 thereby raisingithe link 65, which rocks the arm 42 and moves the lip 40 upwardly from the opening 39 to enable a slip to be inserted in the machine.

The lip 40 has two lugs (Figs. 2 and 3) which project into slots cut into the slip table 36. In this mannerthe opening 39 is obstructed and no slip can be inserted into the machine until after the list key has been depressed, whereupon the lip 40 and the lugs 75 will be raised to permit the slip to be inserted, as before described.

The arm 48 is held in its normal position, with a finger 71 thereof contacting astationary stud 7 6, as shown in Fig. .3, by a spring 74 (Fig. .1) connected'to an arm 73 rigid with the arm 58 which, it will-be recalled, is secured to the shaft55.

It will be seen by referring to Fig. 3, that the bar 68 is provided with radial slots 77 opposite pins 78 of each of the department keys 79. From this it can be seen thatif any key in this bank is depressed, except the list key 43, the bar 68 will not be moved upwardly and therefore the lip 40 will not be raised above the opening 39. This machine is also providedwith two additional banks of departmental keys 79 (Fig. 4) but since there is 'no'bar, similar to the bar 68 adjacent to these banks, depression of any one of these keys will have no effect on the lip 40, and therefore when the machine is operated with any of the departmental keys '79 only, depressed, no slip can be inserted in the machine.

The machine is so constructed that if any one of the departmental keys 79 is depressed, the impression hammer 32 (Fig. 1) wili receive only one operation, and therefore will take only one impression. Since no slip can be inserted when the machine is operated with one of the keys 79 only, depressed, it can be seen that the impression will always be made on the detail strip.

It can be readily seen that any one of the keys adjacent the bar 68 can be arranged to i operate said bar. The only modification necessary to accomplish this is to provide a cam edge 47 opposite the desired keys instead of the radial slots 77. Thus, any one or more of the keys in the control banks may be arranged to displace the lip 40 thereby permitting a slip to be inserted into the receptacle. However, for the purpose of illustration, only the list key is shown herein as being adapted to control the insertion of a slip. If any of the other keys should be so constructed, it would also be necessary to arrange to control the printing hammer so that two impressions would be made upon depression of any of these other keys.

The well known flexible detent 80 is provided for co-operatin with the pin 46 of the list key and the pins 8 of the departmental keys 79 for holding them in their depressed positions. Each detent 80 is carried by a pair of arms 81 and is adapted to release the keys at the end of the operation of the machine, in the usual and well known manner.

Total control Ze'ver Machines of this type are also provided with a total control lever 90 (Fig. 5) adapted to control the machine for total taking operations in the usual and well known manner. In the system herein disclosed, it is desired to print the total taken from any totalizer represented by keys in the first or right hand bank, on a slip. The first position below add (Fig. 4) is the position to which the total lever is adjusted when a total is to be taken from any of the totalizers represented by the keys in the first bank. Since any of these totals is to be printed on an inserted slip, it is necessary to not only open the receptacle by raising the lip 40 out of the path of the slip, but it is also necessary to control the machine so that the printing hammer will take two impressions.

The lip 40 is raised to permit insertion of the slip by a mechanism adjusted by the total. lever. when it is moved to its first position below add.

Pivoted to the total lever 90 (Fig. 5) is a link 95, also pivoted to an arm 96 secured to a spiral segment 97, loosely mounted on the shaft 53. The segment 97 meshes with a spiral gear 99 secured to a shaft 100 sup ported by the frames 56 and 57 and a bracket 101. Also secured to the shaft 100 is a cam 102 (Figs. 1 and 5). Co-operatlng with the cam 102 is a roller 103 carried by an arm 104 pivoted on a bracket 105. The upper end of the arm 104 is connected to the bell crank 61 by a link 106.

Movement of the total lever 90 to its first position below add will, by means of the connection just described, rotate the cam 102 counterclockwise, (Fig.1) thereby camming the arm 104 and link 106 toward the left. This movement of the link 106 will rock the to the arm 60. The arm 60 is held in its normal position against the stud 59, thus holding the link 62 and bell crank 61 in their normal positions. The link 106, being connected to the bell crank 61 will thereforemaintain the arm 104 in such position that the roller 103 will contact the cam 102 when the machine is at rest. However, when the list key is depressed and the bell crank 61 is rocked, the link 106 will rock the arm 104 and remove the roller 103 from the cam 102. But, when the machine comes to rest and the list key is released, the spring 63 will again return the parts to their normal positions in which the roller 103 is against the cam 102. e

The cam 102 is so formed that the only time it will hold the arm 104 in its moved position, is when the total lever is in the first position below add. If the total control lever is moved to any other of its six positions, the

concentric portion of the cam 102 will be opposite the roller 103, and therefore thearm 104 will be left in its normal position as shown in Fig. 1. lVhen said arm 104 is in this position the lip 40 prevents insertion of a slip into the machine.
